Anyone know the location of the block drains to drain the coolant?

I don't think one exists, that's whay there are post about certain techniques people use to try and get as much out of the block as possible.

I talked with Cummins yesterday. They said there ae no block drains, but removing the lower water pump hose lets most of the block colant drain out. He said about 90% comes out doing that.
